Dynamic Rendering with Template Variables 
Using template variables you can create URLs to integrate with other systems by including information about the user’s context.
Template variables are represented by a series of values given the special syntax: @X@object.attribute@X@. These variables are expanded when rendered into their corresponding values. Within the UI, they can be used in portal modules and within the body of content items in courses.
Note that not all of these variables will resolve on all pages. For example, if the page is not inside a course, there will be no course-related variables available.
